/ Application filed June 228,

To allwhomc'twwxyconcera:

Be it known that T, BERNARD F. WEBER, a citizen of the United States, residing at Chicago, in the county of Cook and State of llllinols, have invented a certain new and useful Improvement in Hydrocarbon Burn-. ers, of which the following is a full, clear,

ing had to the accompanying drawings, forming a part of this speclf ication'.

My invention relates to improvements in hydro-carbon burners of the type which are adapted to project and atomize a stream of liquid hydro-carbon by means of a fluid under pressure. The resent invention is an improvement of the burner covered by prior patent granted to me August 14, 1900.

In the operation of burners of this type which are especially adapted to feed low grade fuel oils, the oil passage is liable at times to become clogged or stopped by particles carried into same by the oil or as some times occurs, the oil creates a deposit at the outlet of the oil passage and reduces or completely closes the outlet orifice. These burners are generally used for burning brick, firing boilers and for heating metallurgical furnaces. Interruption of service is undesirable and should be reduced to a minimum. I have provided means whereby. the closing of the burner valve not only operates to close ofl the fluid under pressure, but also shuts off the flow of fuel oil, thus eliminating the necessity of operating a separate valve for this purpose and in addition to this my improved burnerincludes the feature ofvery v simple means for giving access to the relativelyismall oil feed passage in the valve stem so that the burner can'be shut off and the passage opened for cleaning very quickly. Then the oil passage can be easily and quickly clearedand the burner returned to service with but a slight stoppage.

For a clear understanding of my invention and its several advantageous features, attention is directed to said accompanying drawing in which; 4

igure 1 is 'a longitudinal central sectional view of my improved burner; and

Figures 2, 3 and 4: are cross sectional views on the lines 2-2, 33 and 4.-4 respectivelyof' Figure 1.

The burner of my invention comprises a cylindrical casing 1 divided between 1ts ends by a central cross partition 2 into aforward rare. Serial No. teeter.

fluid ressure chamber 3 and a rear fuel oil cham er l.

The fluid pressure chamber 3 is supplied with fluid under pressure, such as steam or compressed air, through the Suppl ipe 5, and the fuel oil chamber is supplied with fuel oil under suitable pressure through the supply pipe 6.

The forward end of the burner is closed by a head 7 which is conical or tapered and is provided with a central orifice or mouth 8 for the escape. of the fluid under pressure from the chamber 3.

The orifice 8 terminates in an outwardly flared portion and at its inner end or junction with the coned wall of the head 7 forms a relatively sharp angular seat 9.

For controlling the flow of the pressure fluid from the chamber 3, ll provide a valve spindle 10 extending centrally through the burner and provided at its forward end with a coned valve head 11, smaller at its forward end than the inner end of the orifice and adapted to enter into said orifice more or less for regulating the flow of fluid pressure and to be seated tightly against the valve seat 9 to close off the flow entirely.

The rear end of the casing is closed by a removable head 12 provided with a central stufling box 13 through which the valve stem projects and by which the escape of fuel oil, at this point, is prevented.

For mounting the stem for longitudinal adjustment I provide a central threaded opening 14 in the middle artition 2 and the stem is provided with a t readed portion15 fitting with-in the threaded opening 14. The partition wall 2 is provided with central extensions 16 and 17 on its front and rear sides so that the threaded contact between the partition and the stem will be long enough to prevent any flow of the pressure fluid or the fuel oil through said joint. The stem carwith a central bore 21 extending from end to end thereof and connected by radial opened portion 15 of the stem and in such position that when the valve stem is screwed forward to seat the head 11 on the valve seat 9 and close off the orifice 8 the feed openings 22 will be carried within the threaded opening 14, as shown in dotted lines, and the fuel oil will thus be closedofl' from the central feed opening 21.

As explained, the central feed opening 21 extends from end to end of the stem, it is shut off or closed at its rear end by a screw 23, the screw 23 provided with a winged head 24 by which it can be quickly 0 erated and with a .fixed collar 25 adapte to be seated tightly upon the extreme rear end of the stem for making a pressure tight joint at this point. The screw 23 serves to plug or stop the rear end of the central oil passage 21, but I depend mainly upon the collar 25 to seal the assage at this point against the escape of t e fuel oil. The collar 25 is large enough in diameter to form a shoulder to prevent the removal of the, hand wheel if it should become loosened on the stem.

In assembling the burner the portion 26 of the stem which fits within the stuffing box 13 slides freely through the threade opening 14.

The forward or outlet end 27 of the passage 21 is flared to correspond with the flaring of the orifice 8 so that the effect of the projection of the central stream of oil within the cone shaped stream of fluid under pressure escaping around the head 11 is to cause the oil to be thoroughly atomized and projected in a spreading cone shaped stream.

- If any stoppage of the burner occurs due to solid particles being carried into the bore 21 or due to the accumulation of carbon at the forward end of the passa e the oil can be quickly and easily shut off rom the bore 21 and radial passages 22 by screwing the valve stem forward, thereby not only cutting off the flow of pressure fluid through the orifice 8 but also shutting off the flow of fuel oil to the central bore 21 by reason of the radial feed openings 22 being carried within the central threaded opening 14 in the central partition. No time is lost in this operation by the necessity of having to close a shut-off valve in the supply pipe 6, which is usually installed so that, in case of necessity, the burner as a whole can be removed for repairs. After the stem has been screwed forward and the flow of pressure fluid and fuel oil has been shut ofl', it is a simple mat ter to open the rear end of the bore 21 by removing the screw 23 and then the passage 21 can be quickly cleared by pushing a wire or rod through the passage from its rear open end,

This operation of cleaning the burner need take but a very short time and the burner any difference.

and can do no can be quickly put back into service by again replacin the screw 23, thus closing the rear end of t e passage 21, and then unscrewing the valve stem to the desired point.

Even if the screwing forward of the stem does not close off the steam altogether, the small leakage'which occurs does not make The same is true of any slight leakage of oil. The steam escapes in a direction awa from the cleaning opening harm. The oil leakage likewise can do no harm to the operator while he is cleaning the bore 21.

As it is ObVlOllS that different embodiments v of my invention can be devised, I 'do not limit or confine m invention to the s eoific structure herein s own and describe excep within the scope of the appended claims.
